HERIP/MRN E. 1113*" TEE P Ell, 01" NEW YORK, 517., AND WILLIAM G. HALL, OF HONOLULU, HAWAII. ASSIGLNORS TO INGERSOLL-BAND COMPANY, OF JEB SEW CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

RECTIFIER AND CONDENSER.

7'0 all whom it may concern Be it known that we Holman E. BEYER and li'iLLiAM G. HALL, both citizens of the United States, residing, respectively, at New York, in the. county of New York and State of New York, and at Honolulu, in the, county of ()ahu, in the. Territory of Ha *aii. have invented a certainnew and useful Improvement in Rectifiers and Condensers, of which the following is a specification.

This invention relates to a. combination rocti'licr and condenser adapted particularly For vacuum drying pans and evaporators used in the procrwss of manufacture of sugar and other chemical processes.

The ob ect of the )rcsent invention is to' provide a rectifier and ondenser in combination with a vacuum pan in which the con- (ltllStl is mounted directly above the vacuum pan and the rectifier is located between the vacuum pan and condenser, or just below the coiulenser, so that the. large amount of piping required for carrying oil the vapors in the apparatus now used is dispensed with and a more ellicicnt installation is provided. With the ahove and other objects in view' our invention consists in the features of con struction and operation set forth in the fol lowing specification and illustrated on the acraijmpanying drawing, lorrniugr a part hereof, in which the ligure shows a. vertical sectional view of the complete installation of vacuum pan rectifier and coi'idenser.

Referring more particularly to the figure, the reference character 1 refers to the vac uum pan or evaporator cell which may be of any usual construction, directly above which is located the rectifier 53 held securely in relation to the vacuum pan by the cone sheet 3. The rectifier 2 comprises a plurality of plates 4 having short lengths of piping: 5 inserted in each, the wipes 5 in each plate 4 being staggered in relation to those in the adioining plates. This is for the pnrposcof providing a tortuous passage for the vapors arising from the vacuum pan and for the purpose of eutropping particles of the commercial fluid to prevent them from being carried oil into the condenser with the vapor. Each of the plates 4 of the rectifier 2 is provided with a central orifice or hole (5 terminating helow tho udu'o ot a. liquid scaling cup 7 and from the central portion of the liquid sealing cup 7 extends a small Specification of Letters Patent.

pipe 8 to drain the commercial liquid back into the bottom of the vacuum pun. Directly above the rectifier 2 is a crown sheet 9 which acts as a hallle for the falling cascade oi water from the condenser 10 press ently to he more definitely described. This is spaced from the rcctiticr 2 by ueans of short struts ll so that there is a large area of opening for the vapors to pass from the rectifier 2 into the lower portion 153 of the condenser. Preferably the condenser is mounted upon an annulus l3 and cone 14 extending: from the walls of the vacuum pan 1 so that the cone sheet and rectifier 2 and crown sheet 9 are all incased within the base of the condenser 10. This is for the purpose of providing an insulating cavity for the top portions of the vacuum pans 0r evaporators and to also provide a portion from which the cooling water may be drained into a drain ipe or cduction or barometric pipe 15. "he condenser 10 is itself: mounted upon the upper surface of the cone it and comprises a counter current condenser of the form descrihcd and claimed in the patent. granted to Herman E. Beyer, i i-1.162069. so that a further description of the pairs of this condenser is not deemed to be necessary. The circulating water is admitted through orifice l6 and the air pump is in communication with the pipe 1'? extending from the top of the condenser to remove any air that may be contained in the solutions. A pipe 18 communicates with the battle chamber 19 to drain any water which may be carried over into this chamber.

From the above description it will be seen that a new arrangement of rectifier and condenser has been provided for an evaporating or vacuum pan in which the vapors arising from the evaporating or vacuum pan pass directly through a rectifier of large area and consequently the velocity of the vapors arising from the evaporating pan is not increased to any. perceatible degree and is therefore very low. rom the rectifier 2 the vapors come directly in contact with the circulating or cooling waters of the condenser without passing, through any additional piping or having their velocity increased by passage through piping of reduced. diameter, so that there is no heat or commercial fluid lost in the piping. The counter current condense-r which as above stated is the type best adapted for the pres ent installation, is arranged so that there is a very slight terminal difference between the temperature of the vapors and thefinal temperature of the cooling water; that is,

there is but little if any difference in temperature between the vapors as they rise from the an and the circulating water as it passes rom the condenser. This has the effect of preventing chillin of the cone sheet 3 and consequently 0011C ensation of the vapors within the evaporating pan, which is one cause of loss due to the'heat required to reiivaporate the vapors condensed.

It is to be understood that the present showing and description disclose only one specific embodiment of our present invention, and that other forms and modifications are included within the spirit and scope of the invention, as expressed in the appended claims.

What We claim is:

1. A combined rectifier and condenser, comprising a vacuum pan, a cone sheet above the same, a rectifier supported by said cone sheet over the vacuum pan, means for draining the rectifier back to the vacuum pan, a. crown sheet spaced above the vacuum pan and acting as a hafiie to intercept cooling liquid, a casing extending above the rectificr, a condenser supported by said casing above the rectifier, means for draining the said condenser casing, baflles in the condenser forming chambers, means for admitting circulating cooling liquid to the condenser and means for draining the upper bnilie chamber of the condenser.

52. A combined rectifier and condenser comprising a vacuum pan, a, cone sheet above the same, a rectifier supported by said cone sheet over the vacuum pan, means for draining the rectifier back to the vacuum pan, a crown sheet spaced above the vacuum pun by struts and acting as a bafile to intercept a falling cascade of cooling liquid from a counter current condenser mounted upon a cone shaped casing extending from the mile of the vacuum pan above the rectifier thereby incasing the rectifier within the base of the-supporting casing, means for draining the cooling liquid from the bottom of the cone shaped condenser supporting casing, means for admitting circulating cooling liquid to the condenser, means for exhaust inn the condenser, baliles in the condenser and means for draining the upper balile chamber of the condenser.

In testimony whereof, we have hereunto set our hands.
